Answer 1

When you queue the job after first call, you will get the Job id. Action poller can be used to Poller ApexAsyncJob with the job id you have to check if job has been completed or not. If completed perform your logic.

If you are making the callout from VF page, i would suggest you have a look at Salesforce continuation framework. It has provision of chaining the callouts so you can think its only one callout while in backend its making another callout.

Chain 1 and 2nd callout and the page will rerender after both calls.
